* INTRNG: only shuffle for !EARLY_AP_STARTUPMitchell Horne2020-07-212-5/+10
| | | | | | | | | | | | | | | | | | | | | | | During device attachment, all interrupt sources will bind to the BSP, as it is the only processor online. This means interrupts must be redistributed ("shuffled") later, during SI_SUB_SMP. For the EARLY_AP_STARTUP case, this is no longer true. SI_SUB_SMP will execute much earlier, meaning APs will be online and available before devices begin attachment, and there will therefore be nothing to shuffle. All PIC-conforming interrupt controllers will handle this early distribution properly, except for RISC-V's PLIC. Make the necessary tweak to the PLIC driver. While here, convert irq_assign_cpu from a boolean_t to a bool. Reviewed by: markj Differential Revision: https://reviews.freebsd.org/D25693 Notes: svn path=/head/; revision=363404

* gpioiic: never drive lines active highAndriy Gapon2020-07-211-11/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | I2C communication is done by a combination of driving a line low or letting it float, so that it is either pulled up or driven low by another party. r355276 besides the stated goal of the change -- using the new GPIO API -- also changed the logic, so that active state is signaled by actively driving a line. That worked with iicbb prior to r362042, but stopped working after that commit on at least some hardware. My guess that the breakage was related to getting an ACK bit. A device expected to be able to drive SDA actively low, but controller was actively driving it high for some time. Anyway, this change seems to fix the problem. Tested using gpioiic on Orange Pi PC Plus with HTU21 sensor.

* iflib: initialize netmap with the correct number of descriptorsVincenzo Maffione2020-07-201-22/+38
| | | | | | | | | | | | | | | | | | In case the network device has a RX or TX control queue, the correct number of TX/RX descriptors is contained in the second entry of the isc_ntxd (or isc_nrxd) array, rather than in the first entry. This case is correctly handled by iflib_device_register() and iflib_pseudo_register(), but not by iflib_netmap_attach(). If the first entry is larger than the second, this can result in a panic. This change fixes the bug by introducing two helper functions that also lead to some code simplification.

| | | | | | | | | | | | | | | | | | | | | | Split the MANAGE privilege into MANAGE, SETMAC and CREATE_VAP. + VAP_MANAGE is everything but setting the MAC and creating a VAP. + VAP_SETMAC is setting the MAC address of the VAP. Typically you wouldn't want the jail to be able to modify this. + CREATE_VAP is to create a new VAP. Again, you don't want to be doing this in a jail, but this DOES stop being able to run some corner cases like Dynamic WDS (DWDS) AP in a jail/vnet. We can figure this bit out later. This allows me to run wpa_supplicant in a jail after transferring a STA VAP into it. I unfortunately can't currently set the wlan debugging inside the jail; that would be super useful!

* amd64 pmap: microoptimize local shootdowns for PCID PTI configurationsKonstantin Belousov2020-07-187-110/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When pmap operates in PTI mode, we must reload %cr3 on return to userspace. In non-PCID mode the reload always flushes all non-global TLB entries and we take advantage of it by only invalidating the KPT TLB entries (there is no cached UPT entries at all). In PCID mode, we flush both KPT and UPT TLB explicitly, but we can take advantage of the fact that PCID mode command to reload %cr3 includes a flag to flush/not flush target TLB. In particular, we can avoid the flush for UPT, instead record that load of pc_ucr3 into %cr3 on return to usermode should be flushing. This is done by providing either all-1s or ~CR3_PCID_MASK in pc_ucr3_load_mask. The mask is automatically reset to all-1s on return to usermode. Similarly, we can avoid flushing UPT TLB on context switch, replacing it by setting pc_ucr3_load_mask. This unifies INVPCID and non-INVPCID PTI ifunc, leaving only 4 cases instead of 6. This trick is also applicable both to the TLB shootdown IPI handlers, since handlers interrupt the target thread. But then we need to check pc_curpmap in handlers, and this would reopen the same race for INVPCID machines as was fixed in r306350 for non-INVPCID. To not introduce the same bug, unconditionally do spinlock_enter() in pmap_activate().
